Detection of speech disorders
Struhař, Michal ; Rajmic, Pavel (referee) ; Sysel, Petr (advisor)
This thesis deals with detection of speech disorders. One of the aims of this thesis is choosing suitable parameterization: short-time energy, zero-crossing rate, linear predictive analysis, perceptual linear predictive analysis, RASTA method, cepstral analysis and mel-frequency cepstral coefficient can be chosed for detections. Next aim is construction of detector of speech disorders based on DTW (Dynamic Time Warping) and artificial neuron network. Single detection proceeds on the base of collected tokens from chosen analysis and phonetic transcription of speech. Analyses, detector and phonetic transcription of Czech language are implemented in simulation environment of MATLAB.

Linear prediciton and cepstral synthesis of speech signal in the TTS system
Mekyska, Jiří ; Stejskal, Vojtěch (referee) ; Smékal, Zdeněk (advisor)
This work deals with a linear prediction and cepstral synthesis of speech signal in the TTS (Text-to-Speech) systems with the opportunity of modeling the prosody. The work contains a description of speech signal in acoustic and phonetic plane, the principle of speech production and the way we can figure the speech signal in time and frequency domain. Next, there is the TTS block structure mentioned, whereas each block has its own detailed description. In the work, the modeling of prosody using the three most important suprasegmental features (fundamental tone, continuation and speech intensity) is also described. At the end of this work, there is a design and realization of universal Czech TTS system which is based on the speech synthesis in frequency domain. This system is implemented in program MATLAB.

Voice Sample database design for speech recognition purposes
Grobelný, Petr ; Malý, Jan (referee) ; Pfeifer, Václav (advisor)
Práce se zabývá rozpoznáváním řeči a tvorbou řečové databáze, která bude sloužit jako trénovací a testovací data pro systém rozpoznávání řeči. Daný korpus je navrhnut jako databáze čtené řeči. V teoretické části je čtenář seznámen s pojmem rozpoznávání řeči a je hlouběji uveden do problematiky. Praktická část se skládá z podrobného postupu vytvoření databáze čtené řeči. Samotná databáze je prezentována na přiloženém médiu. V závěru práce je přiložena potřebná dokumentace celé databáze.

Estimation of accuracy of speech technologies based on signal quality and audio content richness
Nezval, Jiří ; Smital, Lukáš (referee) ; Schwarz, Petr (advisor)
This thesis discusses theoretical analysis of the origin of speech, introduces applications of speech technologies and explains the contemporary approach to phonetical transcription of speech recordings. Furthermore, it describes the metrics of audio recordings quality assessment, which is split into two discrete classes. The first one groups signal quality metrics, while the other one groups content richness metrics. The first goal of the practical section is to create a statistical model for accuracy prediction of machine transcription of speech recordings based on a measurement of their quality. The second goal is to evaluate which partial metrics are the most essential for accuracy prediction of machine transcription.

Phonetic transcription of Czech
Pavel, Lukáš ; Křupka, Aleš (referee) ; Sysel, Petr (advisor)
The goal is to create an application for automatic transcription of Czech language into a phonetic form. The first chapter of this thesis describes the basic phonetic units, alphabets and symbols, that phonetic alphabet uses. The second chapter describes in detail the rules of phonetic transcription of Czech language, including specific examples. Finally, in the third chapter is a description of the application created in C programming language, including flowcharts for better orientation in its functions.

Realization of a speech generator library for embedded systems
Kvasňák, Michal ; Macho, Tomáš (referee) ; Petyovský, Petr (advisor)
The bachelor thesis is about implementation of library which allows to generate voice output using an embedded system Arduino Mega2560 rev3 to which buzzer is connected. The library works on logic obtained by analyzing the „HLAS“ program designed for personal computer Sinclair ZX Spectrum. The output of the work is a working library which is used for lab task designed to learn about USART serial communication interface.

Song lyrics by Jaromír Nohavica in the aspect of dialectology
KUČERA, Jan
The main content of this bachelor thesis is a dialectical analysis of a part of Jaromír Nohavica´s work to describe the influence of the Silesian dialect in his lyrics. The thesis is introduced with a summary of Nohavica´s life and work, followed by the theoretical part consisting of a description of Silesian dialectical features. The practical part contains tables with dialectical occurrences in all linguistic levels, their characterization and analysis supported by examples.
